Hi, did you resolve with your problem on gimbal board? I have the same problemThis is from RC forum translated from Polish is go pro hacking software going to be a help or is this referring to a different part of the software.
Well, it's a pity that the topic is not mentioned that this is about p3 pro / adv. For the 'standard' version the method is known. Generally, in the moments of inspiration, I am slowly picking something up with this topic; first and foremost, I look at the firmware that is part of the drone. It seems that there are a few basic 'types' of components that are in the firmware package in different versions depending on the version of the hardware: main controller ldr main controller app gimbal battery controller electronic speed control radio transmitter vps camera vps sonar FPGA air camera (and camera encoder) video transcoder MCU (I got the name from some Russian which also played with it) For now, I looked at the camera firmware in more detail (it's the largest one - I thought it was from RC before). This is the firmware for the Ambarella A9SE SoC chip, and therefore the same as in the GoPro Hero4. Firmware contains a posix RTOS system, so there is also a network stack - but I do not know if it is controlled by a transciever in the drone. In any case, GoPro is popular and many people are modifying them, hence there are tools to play with this particular block.
